Good, Quiet 1000 gph Pump for Closed Loop?

[stereomandan]

I'll be going closed loop for flow on my new 90g. I'm looking for something equivalent to 4 Maxijet 900's, or roughly 900-1000 gph. The pump needs the capability to be mounted externally of coarse.

Thanks.

You have to account for loosing head. I would go with a 1,200 GPH pump.

Why bother with a closed loop for only 1000gph, if you split that into 4 outlets its not going to do much. Look at something like a sequence dart. Its like skimmers, once you get one you want the next model up, so why not get the one you want the first time.

quiet one pumps are just that... quiet.. i have the 3000 thats pumping about 550 gph at 4 feet of head, but they have a 4000, 5000, 6000, 9000, and 14000 models that pump much more... id say depending on how high you are pumping it the 6000 at about 1500gph should be plenty...

But isn't 1000gph split into four outlets still 1000gph?Isn't the OM Squirt made for closed loops, and it can only handle 1000gph?

well that depends on head pressure of the pump. I got the Super Squirt Compact, I believe it is supposed to take 2,500 but that is not the case with me. I have a BlueLine 70 which pumps at 1,750 GPH, that I cannot use at full blast because it will knock.

I think you will be just fine with the route you are taking.

PanWorld 50 or 100PX-X (the -X is important). I have a PanWorld 50PX which is very quiet (it is the pressure rated version though).

As closest you can get.

quiet
low heat
durable
quality

personaly for my 90 i want about 18000gph 20turnovers/hour.
but im going to settle for a little less useing a blueline 40 hdx and a couple of penductors

Thanks everyone. I ask about a 1000 gph pump because I'm going to see how the flow is, and then if I want more, I'll add another pump for another closed loop system. That way I can put one on a timer and calm it down at night. I can always split the flow into 3 outlets instead of four, and get more volume and velocity out of each.

I'm looking for roughly 250 gph out of each head. I will oversize slightly for head and pressure losses as well. It will only have about 1 ft. of head though.

My sump pump is about 300-400 gph as well.

I'm shooting for about 20x total right now.

You mean 1800 right?

Quiet One 4000 - $60 50W (1017 gph)
Eheim 1262 - $130 ?W (898 gph)
Panworld PW-50PXX $140 90W (1110 gph)
Panworld PW-100PXX $165 110W (1270 gph)

Looks like the Quiet One wins hands down, unless it is unreliable. It's very efficient and is low cost. Anyone have issues with the Quiet One pumps used externally or internally?

QO one pumps are notorious for restart problems and not being quiet. For a CL, I'd use a true pressure rated external pump.

Yeah, I just read up on them. Looks like the Panworlds are a good option then. I think I'll go with a PW- 50PXX

i run my quiet one wet so i dont know about externally, but internally they are quiet... yes sometimes after a sudden restart they have a major increase in noise level but if you unplug it for like 30 seconds and plug it back in it will go back to normal...

 

[antonsemrad]

Due to the way the quite one is made, its not a good pump for a CL. You will have problems with it leaking, and it has no power to pump through bends in your pluming. Plus it's not quiet. I love my quiet one for mixing salt, and water changes. The pan world would be a good choice for the $$. But really, a dart, or sequence, or ampmaster style pump would be best IMHO.

 

[stereomandan]

antonsemrad, isn't the Dart made by Sequence? The Snapper by Sequence is really catching my eye right now. VERY efficient and LOTS of flow. 98W for 2600 gph!

The Dart is more flow than I want though. 3600 gph is pushing it.

By the way, I have lots of family in Appleton. Great city.

O.k., so I re-thought the pump size a little. Now I’m looking at either:

Sequence Dart (3600 gph, 160W max draw) - $200
Sequence Snapper (2500 gph, 98W max draw). - $190

I am going to run this closed loop. It will have only 1’ of head pressure. I am going to run eight ¾” Lock-Line fittings down into the tank off this single pump.

Which pump is sufficient for my 90g? Is 2500 gph divided into the eight outlets going to provide enough flow? That would be nice since it uses much less wattage.

Thanks,
Dan

Anyone?

I have ten 3/4" outlets on a hammerhead. I often close two for more flow from the others, but then again, I'm trying to reach the bottom of a 30" tall tank and still have significant flow down there.

I know it's pricey, but have you considered an OM? Smaller pump, which means less energy, less initial cost (of the pump anyways ), less heat. If I had to do it over, that's what I would do.
